One of the most perplexing questions in the foundations of physics is how our shared sense of reality emerges out of quantum mechanics. This is because in quantum mechanics, it seems, different observers can arrive at different conclusions about what is real and what not. A group of physicists now used an approach called “Quantum Darwinism” to solve this tricky problem. At least they say they solved it. I am not so sure. Let’s have a look.

It features a presentation of a scientific paper on the “Metrological approach to the emergence of classical objectivity,” suggesting a potential solution to a long-standing problem in quantum mechanics. We explore how the “observer effect” and individual “consciousness” play a crucial role in shaping our understanding of “reality does not exist” within the realm of “quantum physics explained.” This deep dive connects the fundamental principles of “quantum mechanics” with profound questions in “philosophy.”
